Biography

    I am a machine learning researcher with research interests in hypothesis testing and transfer learning. My long-term goal is to develop intelligent systems that can learn knowledge from massive related but different domains automatically. Researching on hypothesis testing and transfer learning is the first step for achieving my long-term goal.

    I am a postdoctoral researcher at Australian Artificial Intelligence Institute (AAII), University of Technology Sydney (UTS), Australia, and the recipient of Australian Laureate postdoctoral fellowship. I received my Ph.D. degree in computer science at UTS-AAII in 2020, advised by Dist. Prof. Jie Lu and Prof. Guangquan Zhang.

    I was a research intern with the AI Residency Program at RIKEN Center for Advanced Intelligence Project (RIKEN-AIP), working on the robust domain adaptation project with Prof. Masashi Sugiyama, Dr. Gang Niu and Dr. Bo Han. I visited Gatsby Computational Neuroscience Unit at UCL and worked on the hypothesis testing project with Prof. Arthur Gretton, Dr. Dougal J. Sutherland and Wenkai Xu.

    I have served as a senior program committee (SPC) member for ECAI and program committee (PC) members for NeurIPS, ICML, ICLR, AISTATS, ACML, AAAI, IJCAI, CIKM, ECAI, FUZZ-IEEE and so on. I also serve as reviewers for many academic journals, such as IEEE-TPAMI, IEEE-TNNLS, IEEE-TFS, PR, AMM and so on. I received the UTS-FEIT HDR Research Excellence Award (2019), Best Student Paper Award of FUZZ-IEEE (2019) and UTS Research Publication Award (2018).


Research Interests

    My research interests lie in hypothesis testing and transfer learning. My long-term goal is to develop intelligent systems that can learn knowledge from massive related but different domains automatically (e,g., domains drawn from different distributions). Researching on hypothesis testing and transfer learning is the first step for achieving my long-term goal. Specifically, my current research work center around two major topics:
  • Two-sample testing: How can we know if training set and test set are from the same distribution?

  • Domain adaptation: How can we get accurate predictions when the training set (source domain) is statistically different from the test set (target domain)?
